bindbidirectional vue js

To achieve bidirectional data binding in Vue.js, you can use the v-model directive along with a computed property. Here are the steps to implement it:

Step 1: Create a data property in your Vue instance to store the value you want to bind bidirectionally. For example, let's say you want to bind an input field to a variable called message:

data() {
  return {
    message: ''
  }
}

Step 2: In your template, use the v-model directive to bind the input field to the message variable:

<input v-model="message" type="text">

Step 3: Create a computed property that returns the same value as the data property. This computed property will be used to update the data property when the input field changes:

computed: {
  messageComputed: {
    get() {
      return this.message;
    },
    set(value) {
      this.message = value;
    }
  }
}

Step 4: In the template, bind the computed property to the input field using the v-model directive:

<input v-model="messageComputed" type="text">

Now, when you type in the input field, the message data property will automatically update, and vice versa. This allows for bidirectional data binding in Vue.js.
